It's that time again, folks: Hugh Jackman is pumping iron and packing on the pounds to shape up for the next installment of "Wolverine."

But who has he enlisted for help in achieving that rock-solid physique? Why, none other than The Rock.

"I got the diet from Dwayne Johnson, he put on 25 pounds for his last film and I saw him and was like, 'wow' so I called him up and he gave me his exact diet," Jackman told FOX411's Pop Tarts at the Audi Super Bowl celebration at the Audi Forum in Dallas on Friday evening. "I need to put on about 30-40 pounds, I don't know if I can get there but I am up about 15 pounds so far. I'm trying."

Jackman's Johnson-inspired weight gain diet is comprised of 6,000 calories daily, and believe it or not, but its "hard work" to eat so much.

"Basically it's steak or chicken, broccoli and cauliflower, and sometimes rice but only up until lunch time," he explained. "That's it eight times per day. It's like a job in itself."
